AUTOMOBILE ATTACHMENT.

Specification of Letters Patent. Parenteel July 3l, figli?.

Application tiled February 2511916. Serial ll'o. 80,440.

To all whom it may conffwm Be it' known that I, 'Cox' l). MCCORMACK, a citizen of the United States. residing at ll'aynoka. in the countyv ot' loods and State of Oklahoma,4 have invented certain new and useful Improvements in Automobile Attachments: and I do herebyv declare the following to be a 'luiheid and exact description ot the invention. such as will enable others skilled in the art to which it appertains to make and use the same.

T his invention'rclat'es to attacln'nents for automobiles. and has for its objectto provide a portable device attachahle to the crank shaft of a motor vehicle engine for utilizing the power of the latter in driving farm, shop or other machinery.

Another object is the provision ot' means for rigidlvsecuring the attachment in proper position witlrrelation to the body trame of the motor vehicle'so asto retain the crank shaft'and driven shaft in line.

lilith these and other objects in view7 the invention consists in the novel construction. combination and arrangement of parts as will be hereinafter specifically described, claimed and illustrated in the accompanying drawings. in which:

` ts a tragmental side Figure l represen elevation ot a motorl vehieie. illustrating theattachinent applied to use.`

Fig@ represents a longitudinal sectional view through the attachment removed.

lfig. 3 represents a plan view of one of the attaching elements removed.

Fig. t represents a trout elevation ot vthe attachment.

Fig. 5 represents a longitudinal sectional view through the shatt coupling. and

Fig. G represents a transverse sectional view through the coupling on the line (i-(S ot Fil. il. Y

Referring to the drawing in detail. wherein similar reference numerals designate corresponding parts throughout the several views, the numeral 5 indicates generally the supporting frame ot theattachrnent, which includes a horizontally disposed rectangular Jframe 6 supported atvtlie corners thereof on a plurality of downwardly'diverging supportinglegs 7.; Adjacent their lower ends the legs 7 are connected by the horizontally disposed braces S, which latter are connected by a pair of f spaced horizontally disposed longitudinal braces 9. A ltongue 10 is pivotally secured at il to the bracing member l respectively.

8 at the front end ot' lthe trarne and support-ing axle 1Q is detachably secured adjacent the center and under the longitudinal braces 9 by I bolts 13. rllhc opposite ends of the axle l0 are mounted in the hubs oi" supporting Wheels ll, whereby the frame 5 may be conveniently transported.

The horizontal rectangular' frame 6 includes the side and end members 16 and l?, Bearings 18 are supported upon the end members ll' and rotatably re ceivea driven shaltI lQVhaving a starting "pin in the front end thereof. as indicated at 20, to receive a starting crank for starting the engine of the. motor. vehicle, as will be more fully explained hereinafter. A. plurality ot graduated pairs ot drive and idle pulleys 2l and respectively, arearranged'upon the shaft 19 between the two end members ll of the trame (i andare adapted .to receive the power transmitting belt. whereby the rotary movement of the drive pulleys 2l is transmitted to any desired point.

The rear end ot the crank shaft lil is squared. as indicated at and is snugly fitted in one end ot a shaft coupling 2l, having an angular bore shaped coniorniably with the external contour ot. the Flared end Q3 ot the driven shalt. The. central portion et' the bore ot the coupling '2l is gradually increased in diameter so as to permit slightv universal movement ot the coupln upon the end et the shaft.

Vl`he trame 5 is firmly held in position in iront ot the motor vehicle. designated gcnerally by the numeral bv a plurality o attaching elements. designated generally by the numerals QF. ear-h attaching element in- A pair of guides ,.53 aresecured in spaced relation 'upon one of the'side members lbllt of the rectangular traine 6 and receive a slide bar 3l, having a handle at one. end

and a plurality of pairs of belt shifting fingers 36 adapted to embrace a drive belt arranged over one of the pulleys 21 or 22 to shift the latter from the driving to the loose pulleys.

In moving the automobile attachment to andfrom the vehicle, the axle 12 is attached to the longitudinal braces 9 by the 1 bolts 13 so as to facilitate convenient transporta 'tion of the attachment. When in use, the axle 12 and Wheels 14 are removed and the driven shaft 19 is coupled with the drive shaft 32 by the shaft coupling 211. Tliefframe 5 is secured to the-frame of the motor ve hicle in such position as to axially line the driven shaft 19 with the drie shaft 22 by clampingr the rear brace 8 between the screws 29 and also clamping the axle 31 between the screws 29 at the opposite ends of the attaching bars 27. In order to start the vehicle propelling engine when the attachment is connected with the crank shaft 32 thereof the usual type of starting crank is applied to the starting pin of the driven shaft 19 and rotated so as .to operate the engine.

lVhat I claim is:

' 1. An automobile attachment including a supporting frame, a shaft mounted in said frame, attaching bars, means for attaching one end of the bars to the frame, adjustable means forl attaching the opposite ends of the bars to a vehicle axle, andmeans for attaching said shaft to the crank shaft of a motor vehicle engine.

2. An automobile attachment including a frame including supporting legs and horizontal braces connected therewith, support ing Wheels detachably connected with said frame, means for attaching said braces to the axle of a motor vehicle, a drivenshai't rotatably mounted in said frame, and means for connecting vsaid driven shaft With the engine shaft of the automobile.

3. An' automobile attachment including a supnortinar frame, a driven shaft mounted in said frame, attaching bars, laterally projectingz, ears arranged in pairs adjacent the COY D. MCCORMACK.
